In a new installation, as I stated above, the installer will go to GREAT lengths to avoid the attic, crawl spaces, or fishing between walls. If you're picky about which holes get drilled where, you're best doing it yourself before the installer gets there, allowing him to focus on getting the signal into your house and the receiver programmed properly.

Agree 100%
Been installing for 4 years now and that's the worst that a customer can do. Be to picky. I get that some customers want there install a certain way. A good installer will give you many options on where the dish needs to go or how to run the sat lines. What I've learned in the past is good communication with the customer goes a long way when your in there house. Just my 2 cents worth.
